Specification of Letters Patent.

Patente'dFeb. 24, 1914. 1913. Serial No. 781,115.

face of the club with a glass face dovetailed into the wood or other material of the club head with the intervention of suitable cement or packing to allow .of expansion. I have found that a club provided with a glass face as described is extremely efiective and better results can be attained than with the ordinary clubs as now used. It is to be noted that the-glass face must not be held in place by engagement with pins, screws or the like as it is found 'that such arrangements result in splitting or breaking of the glass face.

Figures 1 and 2 show a driver head according to this invention in face view and a is the wooden head formed with a tapering recess the edges of which are dovetailed as indicated b the dotted line bto correspond with the e ges of the glass platec. The plate a is bedded on packing at such as chamois leather and the edges of the plateare coated with a packing of putty-like cement so as to permit the glass plate to expand without fracture; the packing has not the function of a spring cushion. When the plate c has been inserted it is held in place by the attachment of the horn e of the club.

The head of the club is formed with one or more holes pierced from the face of the club to the back which is not broadly new but I find that theresistance of the air upon the face of the club when driving a ball is much reduced by forming holes f as .illustrated .and a correspondingly better result is attained by the player.

What I claim is: v

1. A golf club having a glass striking face plate dovetailed into the materialof the club head and interposed packing to allow -of expansion of the glass, substantially as described.

2. A "olf club, comprising a head formed with a o'vetail recess in its front face and having its end. walls converging toward the upperend of the head, a glass striking face fitting within said recess and a horn carried by the lower face of the head and extending across the lower end of the dovetail recess and engaging the glass striking face and holding the same in the dovetail recess.

3. A golf club having a glass striking face secured therein and having a backing of elastic material. 7

4. A golf club having a glass striking face secured therein and. having a backing of elastic material and a packing at the ends: to allowlofthe expansion of the glass.

5. A golf club having a dove-tailed recess, a glass striking face within the dovetailed recess. an elastic backing between the rear face of the glass face and the club and a packing at the ends to allow of the expansion of the glass.

Signed at London, England this 12th day of July 1913.
